“…The results obtained by Foschini et al [27] allowed to conclude that the electropolymerization mechanism is very similar to the one of pyrrole, as reported by Dias et al [28]. The final polymeric chain will present a torsion angle between subsequent monomeric units of 74°, compared to 54° of pyrrole [27]. Thus, the electropolymerization conditions already reported and studied for pyrrole can also be applied to the polymerization of Py-2-COOH.…”

“…Among the pyrrole derivates, pyrrole-2-carboxylic acid (Py-2-COOH) was less employed in electroanalytical applications [24][25][26], even possessing many sought-after characteristics compared to the parent compound pyrrole, such as the presence of the carboxylic acid functional groups which can be used to couple amide-bearing molecules to the surface via EDC/NHS chemistry. The complete characterization of the electrochemical polymerization pathway of Py-2-COOH has been previously reported [27]. The results obtained by Foschini et al [27] allowed to conclude that the electropolymerization mechanism is very similar to the one of pyrrole, as reported by Dias et al [28].…”

“…However, the main disadvantage of pyrrole is the lack of functional groups. The functionalization of the polypyrrole based film can be made either by copolymerization of the pyrrole with modified monomers or by entirely replacing the monomer with a functional one . Thus, pyrrole 3‐carboxylic acid (P3CA) was used to generate a nanostructured functionalized film.…”

Poly‐(pyrrole‐3‐carboxylic acid) Based Nanostructured Platform for the Detection of Carcinoembryonic Antigen

A nanostructured platform based on pyrrole 3‐carboxylic acid was developed and it was used for the detection of carcinoembryonic antigen, a biomarker for gastro‐intestinal tract cancers. The conductive polymer offers possibilities for functionalization due to the presence of the carboxylic group. The platform was tailored by polymerizing pyrrole 3‐carboxylic acid at the surface of a graphite‐based screen‐printed electrode by using multiple pulse amperometry and cyclic voltammetry. The carboxylic groups were activated, facilitating the formation of amide covalent bonds with the terminal amine groups from the antibody. Each step's optimization was tracked by performing electrochemical impedance spectroscopy. The immunosensor was successfully applied for the detection of carcinoembryonic antigen in synthetic samples. By comparing pyrrole 3‐carboxylic acid with pyrrole, significantly greater increases of the charge transfer resistance were achieved by using the functionalized monomer for the immobilization step. The binding of the anti‐CEA was reproducible and directly proportional with its concentration. The increase of the charge transfer resistance after the incubation with carcinoembryonic antigen was linearly correlated with the concentration of the sample and the LOD was 33.33 pg mL−1. A simple nanostructured platform for the label‐free detection of a carcinogenic biomarker molecule was developed, thus holding great opportunities for clinical diagnostics and other biosensor applications.

“…Recently, chemically synthesized polymers, conductive polymers, sol-gels, metal oxides, self-assembled monolayers and nanocomposites, along with different biomolecule immobilization strategies and polymer modifications have been used to achieve enhanced electron transfer rate [3]. Conducting polymers such as polypyrrole, polythiophene, and polyaniline have been studied in recent years mainly because of a variety of applications found for these materials in enzymatic fuel cells (EFC) and sensors [4]. Polypyrrole-2-carboxylic acid has proved to be an electroactive material with interesting properties for use in EFC.…”

Enzymatic biofuel cells (EFCs), which employ enzymes as a catalyst, convert the chemical energy released from the enzymatic oxidation of fuel into electrical energy. While chemical energy is being generated by the oxidation of fuel with enzymes, electricity is generated simultaneously by the movement of electrons released as a consequence of this chemical reaction from anode through cathode in enzymatic fuel cells. The major problem encountered in EFC studies is the difficult/slow electron transfer between the enzyme and the electrode. To mediate the electron transfer between the enzyme and the electrode's surface, low molecular weight redox compounds called mediators are used in EFC. Higher power generation and minimal interference effects at a lower cell potential are achieved by using a mediator in EFC. The scope of this study is for the development of an enhanced electron transferred EFC with a proper mediator for the generation of electrical energy by the oxidation of glucose in domestic wastewater. Therefore, glucose in domestic wastewater is utilised for energy generation. In this study, Polypyrrole-2-carboxyclic acid was modified with various mediators such as, ferrocene, neutral red and p-benzoquinone, which were tested for this purpose. The maximum power density (100 nW/cm 2 ) was observed for the ferrocene modified electrodes including glucose oxidase and laccase as anodic and cathodic enzyme, respectively. The electrode fabrication step was optimized with respect to the electrode material, its operational potential and the thickness of the polymeric film. The highest current values were obtained from the addition of 10 mM of glucose for the EFC system designed with the gold electrode material and operated with a working potential of 0.45 V. The most suitable polymeric film thickness was achieved in the cyclic voltammetry parameters set up with a scan rate of 50 mV/s and 25 cycles. The
